An earthquake struck off the southeast coast of Taiwan on Monday, causing buildings to sway briefly but no casualties or damage. The temblor was felt at the site of a massive landslide in northern Taiwan but did not hamper rescue efforts. The 6.5-magnitude quake hit at 10:59 a.m. (0259 GMT), 195 miles (295 kilometers) off the southern Taiwan city of Taitung at a depth of 6.2 miles (10 kilometers), the U.S. Geological Survey said. The agency's initial report had put the quake's magnitude at 6.9. In Taipei, buildings swayed for up to 20 seconds when the quake hit, but police said there were no reports of casualties or damage anywhere on the island. No tsunami alert was issued, the Associated Press reported. In northern Keelung county, 18 miles (30 kilometers) northeast of Taipei, the tremor caused little new damage at the site of a massive landslide, police said. On Sunday, a hillside collapsed onto a three-lane highway following several days of rain, burying three cars. Many of the hundreds of workers digging through the rubble felt the temblor but went on searching for the four passengers believed to have been buried in the cars, police said.
